Freescale Semiconductor
Product Brief
Low Cost Integrated Multiprotocol Processor
Freescale introduces the low cost version of the well-known MC68302 Integrated Multiprotocol Processor (IMP).
It will be known as the MC68LC302, and will expand a family of devices based on the MC68302.
Some features and pins have been removed while other features have been enhanced as compared to the
original MC68302. Simply put, the MC68LC302 is a traditional MC68302 with a new static 68000 core, a new
timer and low power modes, but without the third serial communication controller (SCC). It is packaged in a low
profile 100 TQFP that requires less board space than the regular MC68302, as well as making it suitable for
use in height restricted applications such as PCMCIA.

    ... Freescale Semiconductor, Inc. MC68LC302 APPLICATIONS The MC68LC302 excels in several applications areas. First, any application using the MC68302,but not needing all three serial channels is a potential candidate for the MC68LC302. Note however, that the MC68LC302 sacrifices most of the provision for external bus mastership, thus the MC68LC302 may not be appropriate where the MC68302 is used as part of larger systems ...

    ... Freescale Semiconductor, Inc. • The SCP pins are now muxed with PA8, PA9, and PA10. The TXD3, RXD3, and RCLK3 functions asso- ciated with SCC3 are eliminated. • The UDS, LDS, and R/W pins are not available except in slave mode, where they replace the IPL2-0 pins. ...
